active printing
As the name suggests, our printing dyes are processed through reactive printing. The design elements of reactive printing are quite diverse: plants and flowers, geometric figures, English letters and different color blocks are organically combined to show different design styles through design techniques. This kind of fabric is suitable for a wide range of people and has a long application time. The reactive printing fabric has bright color, good color fastness, soft hand feeling, can be washed frequently without fading, and looks like new after long-term use.
Generally, reactive printing and dyeing can ensure that it is environmentally friendly and harmless to people, and the color and fabric feel better without hard or soft feeling.
pigment printing
It uses thermosetting or thermoplastic synthetic resin as a binder, mixed with insoluble pigments to make pigment printing paste, which is applied to the surface of the fabric by mechanical or manual methods, dried and baked to form a film, so that the pigment can be tightly covered on the fiber , to achieve the purpose of printing and coloring. Pigment printing color paste is generally composed of color paste, adhesive, optical coupling agent and latex color paste, which can be mixed when used.
Pigment printing is the printing method with the lowest cost in printing production, because pigment printing is relatively simple, requires the least process, and usually does not need steam washing and water washing. The paint is bright and rich in color and can be used on all textile fibres. Their light fastness and dry cleaning fastness are good, even excellent, so they are widely used in decorative fabrics, curtain fabrics and clothing fabrics that require dry cleaning. In addition, the coating hardly produces a large color difference on different batches of fabrics, and the hiding power of the base color is also very good when covering the printing.
With repeated washing or dry cleaning, the pigment print will gradually fade and the color will become lighter. This is due to the constant rotation and stirring during the cleaning process, which causes the resin adhesive to gradually fall off. Generally, after washing 20-30 times, this printed cloth will have obvious fading phenomenon. Due to the application of resin and silicone softener in the finishing process, the color fastness of the fabric is improved. It's worth noting that dark colors tend to fade more easily than light or light colors.
The paint makes the printed part of the fabric feel hard, which is not obvious in light colors, but very prominent in dark colors. The paint is not particularly hardwearing and the color is particularly dark. Fabrics such as furniture upholstery should especially avoid dark paint.
the difference between the two
1. The process is different
Pigment printing uses thermosetting or thermoplastic synthetic resin as a binder, mixed with insoluble pigments to make a pigment printing paste, which is applied to the surface of the fabric by mechanical or manual methods, dried and baked to form a film, so that the pigment can be tightly covered. Fiber, to achieve the purpose of printing and coloring.
Reactive printing: During the printing and dyeing process, the active groups of reactive dyes are combined with fiber molecules, so that the dyes and fibers form a whole.
2. Different characteristics
Reactive printing and dyeing means that no azo and formaldehyde are added during the printing and dyeing process, no substances harmful to the human body are contained, and the color does not fade when washed. The color and fabric feel are good, not hard or soft.
Pigment printing: The printed fabric is bright and bright in color and has good light stability. It can give the fabric a plump, dry and soft feel, especially excellent rubbing fastness. The dry and wet rubbing fastness can reach ≥4 (for reference only) if used correctly. Excellent washing fastness and good air permeability of the fabric.
how to choose
The production process of pigment printing and reactive printing is used to illustrate which printing is better: most machines can spray paint ink directly on textile fabrics. Applicable models are direct-injection belt guide machines, and the production process is simple and clear. Generally, the production process using reactive ink needs to go through printing - direct injection - washing water - steaming - washing water. Generally speaking, it needs to go through pre-processing and pre-processing of the process, and the production process is complicated. There are generally many pigment prints.
You can judge which is better by the color fastness of pigment printing and reactive printing: the color fastness of reactive printing is generally 4-5 grades, and whether it needs to be faded generally depends on whether the washing water rubs the color and whether the high-temperature blisters fade. The color fastness of the paint is generally grade 3, and the color will not fade when washed by a washing machine. Generally speaking, from the perspective of color fastness, the color fastness of reactive printing is relatively good.
Brightness indicates which is better: pigment printing or reactive printing: the reactive ink can penetrate into the fiber and the color is very bright. Lacquer ink generally penetrates into the surface of the fiber, and the brightness is relatively weak compared with the activity.
Explain which printing is better from the perspective of environmental protection: the pigment ink jet printing process is generally printed on the front of the cloth, which is easily decomposed by nature and fully meets the environmental protection requirements. Reactive printing penetrates into the front and back of the fabric, which is difficult to decompose in nature and is not environmentally friendly. At present, the theme of environmental protection is advocated internationally, and pollutants are strictly controlled. Therefore, what is not allowed by the market is not allowed. We choose pigment printing more.
In terms of production cost: the production process of the event is very responsible, the production cost is high, a lot of machines are needed, and the finished product is also very expensive. The relatively active pigment printing process is very simple and the cost is relatively low. So you know what printing you choose.
